Seems quiet, so I'll through this out:
trying to remotely troubleshoot an ethernet link issue, and have come
across an issue
where my sbus happy-meal quad card is reporting a link-state of up, even
with no
network cable plugged in.
Also, the net 'state' always stays unknown, even on the primary link
that is up/up and working.
granted, all of this is from the sysfs point of view.
Using ethtool, however, the status appears to be correct; not quite sure
why the two sides of the coin
are out of sync....
anyway, not a big problem, just a 2cents...
